Method Detail

setUdpBinding

public void setUdpBinding(UdpBindingService udpBinding)

Description copied from interface: UdpMessageQueueService

Injects the UDP binding service.

Without a UDP binding service the message queue cannot send and receive messages. Make sure the UDP binding is injected before the service is started.

Specified by:

setUdpBinding in interface UdpMessageQueueService

Parameters:

udpBinding - the UDP binding service to inject.

sendMessage

public boolean sendMessage(UdpMessage message)

Description copied from interface: UdpMessageQueueService

Queues an outgoing UDP message.

Specified by:

sendMessage in interface UdpMessageQueueService

Parameters:

message - the message to be send.

Returns:

true if the message could be queued, otherwise false (queue overflow).

registerUdpMessageQueueObserver

public void registerUdpMessageQueueObserver(UdpMessageQueueObserver observer)

Description copied from interface: UdpMessageQueueService

Registers an observer to receive incoming UDP messages.

Specified by:

registerUdpMessageQueueObserver in interface UdpMessageQueueService

Parameters:

observer - the observer to register.

unregisterUdpMessageQueueObserver

public void unregisterUdpMessageQueueObserver(UdpMessageQueueObserver observer)

Description copied from interface: UdpMessageQueueService

Unregisters an observer to stop receiving incoming UDP messages.

Specified by:

unregisterUdpMessageQueueObserver in interface UdpMessageQueueService

Parameters:

observer - the observer to unregister.

startUp

protected void startUp()
                throws Exception

Specified by:

startUp in class com.google.common.util.concurrent.AbstractIdleService

Throws:

Exception

shutDown

protected void shutDown()

Specified by:

shutDown in class com.google.common.util.concurrent.AbstractIdleService

receive

public void receive(UdpMessage udpMessage)

Description copied from interface: UdpMessageReceiverCallback

Receive one incoming UDP message.

Specified by:
